I hard wired several of these cables to my street and dirt bikes (BMW 800 GS, KTM 530, Husqvarna 310) for use with a Garmin Nuvi 550 and Oregon 450 T. They work well but prior units have failed. I traced the failure to breakage of the small internal wires due to shock and vibration. Riding aggressively off road creates quite a bit of shock and vibration. I suggest that if you use any of these small usb cable units on a motorcycle that prior to use, remove the box cover (2 small screws) and apply clear silicone sealant to the tiny wires and other internal pieces to secure them. Let dry, then reinstall the cover and you are ready to go. An added benefit to the silicone treatment is that it resists water which can also cause failure. Since going to this bit of extra effort i have had no problems and my GPS units work well. I would have rated 5 stars if the usb came pre-sealed and treated but then it probably would cost more. Overall these work great and the price is very reasonable.

Requires a little bit of wire stripping and soldering, as should be expected with a hardwire install. Works great with a Garmin Nüvi 1490T. Unlike some vehicle power solutions, it doesn't send the Nüvi into USB mode. The toroid makes it a little difficult to snake the cable through your vehicle, but it's not too bad. It would be nice if the plug was a right-angle.

Good solution for those who want to hard wire a charger (without using an accessory/cigarette lighter plug). I would have rated it 5 stars if the box that contains the circuitry had been a little smaller.

I wired this into my motorcycle to power my Garmin and it worked well for about 6 hours. After that, my Garmin Nuvi 765T started reporting "Accessory connected to wrong port" every few minutes and stopped charging. I ended up ripping out this charger and replacing it with the OEM Garmin charger http://www.amazon.com/gp/product/B0086CTL5Y/ref=cm_cr_ryp_prd_ttl_sol_5 with leads soldered right to contacts and then wrapped in electrical tape. The OEM charger works much better.

The product is ok but I wish the box was smaller I couldn't fit it in the A-Piller so I had to hide it in the roof liner. This shortened all the wires and it barely made it to the fuse box. Also it would be nice if the plastic around the USB connector wasn't so thick. The TomTom has a recessed connection to you have to shove it in there and hope it fits.
